Ka-Pow: Watch These Fish Cannons Shoot Salmon Safely Over Dams

Salmon have serious swimming skills—some travel thousands of miles to return to their original homes to breed. But even though they can jump as high as 12 feet in the air, they can’t manage to get over massive concrete dams that we have built to block their journeys back to their homes. Now one new idea could give them a boost. The plan involves whisking the fish through a long vacuum tube at speeds up to 22 miles per hour and then shooting them out the other end like a cannon.

World’s languages traced back to single African mother tongue: scientists.
New Zealand researchers have traced every human language — from English to Mandarin — back to an ancestral language spoken in Africa 50,000 to 70,000 years ago.
Scientists say they have traced the world’s 6,000 modern languages — from English to Mandarin — back to a single “mother tongue,” an ancestral language spoken in Africa 50,000 to 70,000 years ago.
New research, published in the journal Science, suggests this single ancient language resulted in human civilization — a Diaspora — as well as advances in art and hunting tool technology, and laid the groundwork for all the world’s cultures.
The research, by Quentin Atkinson from the University of Auckland in New Zealand, also found that speech evolved far earlier than previously thought. And the findings implied, though did not prove, that modern language originated only once, an issue of controversy among linguists, according to the New York Times.
Before Atkinson came up with the evidence for a single African origin of language, some scientists had argued that language evolved independently in different parts of the world.
Atkinson found that the first populations migrating from Africa laid the groundwork for all the world’s cultures by taking their single language with them. “It was the catalyst that spurred the human expansion that we all are a product of,” Atkinson said, the Wall Street Journal reported.
Atkinson traced the number distinct sounds, or phonemes — consonants, vowels and tones — in 504 world languages, finding compelling evidence that they can be traced back to a long-forgotten dialect spoken by our Stone Age ancestors, according to the Daily Mail.
Atkinson also hypothesized that languages with the most sounds would be the oldest, while those spoken by smaller breakaway groups would utilize fewer sounds as variation and complexity diminished.
The study found that some of the click-using languages of Africa have more than 100 phonemes, or sounds, whereas Hawaiian, toward the far end of the human migration route out of Africa, has only 13, the Times reported. English has about 45 phonemes.
The phoneme pattern mirrors the pattern of human genetic diversity as humans spread across the globe from sub-Saharan Africa around 70,000 years ago.

This gives me LIFE from people who insist all languages (ALL no matter what) derive from latin bases.

Reblogging this for three reasons:
1) It’s awesome and worth knowing
2) It makes sense when you think about, you know, the whole history of human development (from a NOT white supremacist perspective at least)
3) To add that if anyone ever tries to say that all languages are derived from Latin [insert choked sound of disbelief and anger] you can inform their ignorant (probably racist) asses of this: Latin, as far as languages go, is an INFANT. It’s part of a subset of Indo-European languages and MOTHERFUCKER EVEN ENGLISH ISN’T ONE OF ITS DERIVATIVES. (French, Spanish, Italian, Romanian, and Portuguese are, as well as lots of their related languages and dialects, that’s it.) Latin isn’t even remotely old enough to be a mother language. It’s like saying alpacas were the original dinosaurs or some bullshit.

HUH! You dont FUCKING SAY?
WILL YOU LOOK THE FUCK AT THAT! 

Not surprising, but this is cool information!

In The Not So Distant Future, Glow-In-The-Dark Trees Could Replace Street Lights

Is that… is that even healthy?

There are sea organisms and fungi which glow in the dark and there’s fireflies and jellyfish which glow in the dark. It doesn’t do them any harm nor does it do the people around them any harm. I would say its pretty healthy, as well as it would mean more photosynthesis happening in cities which mean cleaner air.

I was just curious about how they were doing it and for some reason I didn’t think to click the link. But thanks! It makes more sense now. I was afraid it was some kind of chemical thing.

nah just genetic modification using existing bioluminescent genes. Genetics is really cool, and so is bioluminescence. I mean they’ve already made pigs glow using jellyfish genes and pigs are waaay more complicated than trees iirc. So they’re actually (i think) less likely to muck it up with trees.

In which case

GLOWY

FORESTS

GLOWY

TREES

GLOWY

EVERYTHING

(I like glowy things)

I’m hoping they do this safely in a way that doesn’t make the trees extra susceptible to diseases. Like I know some scientists were breeding a kind of fish that glows under black light or something like that, and they were breeding them in such a way that they got sick really easily (breeding them through incest). I hope that doesn’t happen. (I just hope the trees are safe and stuff ahhh)

Bhāskarāchārya

[x], [x]

Bhāskarāchārya / Bhāskara II (1114–1185) was an Indian mathematician and astronomer.

Among his many achievements are the following:

1. He was the first person to explain that when you divide by zero, the result is infinity.

2. He was also the first person to note that a positive number has two square roots - a positive and a negative one.

3. He described the principles of differential calculus 500 years before Leibniz and Newton. (He definitively came up with Rolle’s theorem half a millennium before Rolle himself.)

4. He calculated the length of the rotation of the earth around the sun to 365.2588 days - he was just off by 3 minutes.

Intriguingly, his treatise on arithmetic and geometry, Līlāvatī, is named after his daughter. He addresses her as an eager student:

Oh Līlāvatī, intelligent girl, if you understand addition and subtraction, tell me the sum of the amounts 2, 5, 32, 193, 18, 10, and 100, as well as [the remainder of] those when subtracted from 10000.” and “Fawn-eyed child Līlāvatī, tell me, how much is the number [resulting from] 135 multiplied by 12, if you understand multiplication by separate parts and by separate digits. And tell [me], beautiful one, how much is that product divided by the same multiplier?

These invocations have led some to surmise that Līlāvatī, too, was a mathematician.

This submission is for Science Week I did a project at the physics library where I work. I found quotes from people in physics or that related to math or science in some way, and…

I’ve said this before and I’ll point it out again -

Menstruation is caused by change in hormonal levels to stop the creation of a uterine lining and encourage the body to flush the lining out. The body does this by lowering estrogen levels and raising testosterone.

Or, to put it more plainly “That time of the month” is when female hormones most closely resemble male hormones. So if (cis) women aren’t suited to office at “That time of the month” then (cis) men are NEVER suited to office.

If you are a dude and don’t dig the ladies around you at their time of the month, just think! That is you all of the time.

And, on a final note, post-menopausal (cis) women are the most hormonally stable of all human demographics. They have fewer hormonal fluctuations of anyone, meaning older women like Hilary Clinton and Elizabeth Warren would theoretically be among the least likely candidates to make an irrational decision due to hormonal fluctuations, and if we were basing our leadership decisions on hormone levels, then only women over fifty should ever be allowed to hold office.

Kikunae Ikeda
[x]
Kikunae Ikeda / 池田 菊苗 (1864-1936) was a Japanese chemist and the inventor of MSG. (To all you haters: because Chinese restaurant syndrome has been debunked.)
He was also the first scientist to realise we have five basic tastes, not four. Before his time, Western science had accepted that our tongues have receptors for the following tastes:
1. sweetness
2. sourness
3. saltiness
4. bitterness.
 In 1909, he pointed out that there was a missing taste:
5. umami, or savouriness - i.e. the proteiny taste of meat or cheese or mushrooms or eggs.
This is kind of a big deal. It’s like pointing out that we have five fingers on each hand when Western science is only counting four.
So why the hell are we still teaching schoolkids that there are only four tastes, 105 years after that’s been proven wrong? Don’t we want them to understand why bacon is delicious????

New device allows brain to bypass spinal cord, move paralyzed limbs

For the first time ever, a paralyzed man can move his fingers and hand with his own thoughts thanks to a new device. A 23-year-old quadriplegic is the first patient to use Neurobridge, an electronic neural bypass for spinal cord injuries that reconnects the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb.
